Sandbagging in sales, a common but damaging strategy, involves intentionally delaying closing or reporting deals to lower expectations.Sellers engage in sandbagging to avoid pressure from management, end a sales period strongly, or gain momentum for the next period.Sandbagging is not advisable as it can jeopardize deals, harm team trust, and damage one's reputation and credibility.Instead of sandbagging, experts recommend focusing on effective account planning to improve understanding and achieve better sales forecasts.
